STORE SERVICE APPARATUS.

$PECIPICATION forming part of Letters Patent No. 390,853, dated October9, 1888.

Application filed May 28, 1888.

To all whom it may concern.-

, Be it known that 1, WILLIAM HENRY Goa NALL, of Baltimore, in the Stateof Maryland, have invented a new and useful Improvement in Store-ServiceApparatus; and I do hereby declare that the following is a full, clear,and

exact description of the same.

My invention is an improvement in that class of store-service orcash-carrier apparatus in which the carrier is moved to and fro upon afixed wire practically horizontal. Its main feature is a flexibleextension of this fixed wire provided with a catch and with a raisingand lowering end and pulley, the flexible extension serving to receiveand lower the carrier, and with its connections, heretofore referredto,to raise and impel it along the wire.

In the accompanying drawings, Figure 1 rep resents my invention in sideelevation, and Figs. 2, 3, and 4 show details hereinafter explained.

- In the drawings, A represents a part of the main conveying-wire. It isattached to the rigid track-extension B, which is supported on the lowerend of a bracket, G, all of which is shown more clearly in the frontView of Fig. 4:. The bracket is fixed to the lower end of a rod, D,extending from the ceiling. To the rear end of the track-extension Bisattached the flexible part of the track extension marked E. This is ofspecial form, designed to permit flexibility only in vertical plane andin a limited curve. It is composed of double links a and single linksI), the ends ofthe single links being riveted between the ends of thedouble links. In order also that part of the flexible extension next tothe rigid part may maintain a proper curve, the single links have points6, which extend between studs cl on the inner faces of the double links.This limits the flexure and maintains a proper curve when the pointsbear on the studs, as shown in Fig. 3.

The free end of the extension E is provided with a hook, F, pivoted onthe downwardlycurved end of the last link. This hook is turned inwardlyand underneath the extension. The tail of the hook is also bent towardthe extension on the upper side, as shown at f. On the upper end of therod D is a bracket,

the other, depending, has a handle, it, or this depending part may, asshown, include a knot, Z. The two pulleys allow the cord to play outsideof the track extension and carrier. When the handle is drawn down, theend of the trackextension is raised to the pulleys.

Supposing the extension to be down, as shown in dotted iines, Fig. l,the carriage M, approaching, will run off the wire over the rigid part Band upon the flexible part, and the momentum of the carrier will causeit to strike the tailf ofthe hook F, which is thereby thrown forward toengage with a cross-bar, 0, on the lower part of the carrier frame ateach end. This holds the carrier at the end and retains it in the lowposition, when the contents may be taken from or placed in the box 1?.From this position the carrier may be sent to the other end of the wayby simply pulling on the cord. This raises the extension and carrier,still hooked thereto, to the position shown in full lines in Fig. 1.When the extension reaches its uppermost limit, the tail of the hookstrikes a projection, g, on the upper bracket, which releases thecarrier and allows it to descend by gravity. The momentum acquired inthe descent is sufficient to impel it to the other end of the way.Manifestly the height to which it is to be raised may easily beproportioned to the distance to which it is to be impelled. The end ofthe extension is held up by the operation, and as soon as the handle isreleased the extension sinks to the position shown in dotted lines,where it is ready to receive the carrier on its return. The flexibleextension assumes the position which may be regulated by the knot Zonthe cord, which stops the descent and holds the end of the extension inthe curve shown. The position of the knot will determine the height ofthe end of the extension. The tail f serves as a stop for the carrier aswell as to throw the hook into engagement.

The rod D is braced by a wire, S, which is connected to the rod by wires8 s, between yokes T 25, whereby the wires are clear of the IOOunderstood that the apparatus may be used at one end only, or it may beduplicated for the other end.

I claim as my invention- 1. In combination wit-h a rigid way instoreservice apparatus, a flexible extension formed of links andflexible only in a Vertical plane, substantially as and for the purposedescribed.

2. In combination with the rigid way, the flexible extension formed oflinks, said links having stop projections formed thereon,whereby thevertical movement of the extension is limited, substantially asdescribed.

3. In combination with the rigid way, the flexible extension formed ofdouble and single links, the double links at having studs (1 upon theirsurface, and the single links 6 having points 0 extending between thestuds (1, substantially as described.

4. In combination with the rigid way and the flexible extension, thepivoted hook on the end of the flexible extension adapted to engage withthe carrier for holding the same, substantially as described.

5. In combination, the rigid way, the flexible extension, the upperpulleys and cord,and a hook pivoted on the flexible extension to engagewith and hold the carrier, and a stud, q, in line with said hook formoving the same, substantially as described.

6. In combination,the rigid extension B, the wire A, the flexibleextension, the cord, the pivoted hook on the end of the extension, thepulley, and the upper bracket, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WVILLIAM HENRY GORNALL.
